flotation process mining of zinc

Lead and Zinc - Department of Energy- flotation process mining of zinc ,essentially a co-product of zinc mining or a byproduct of copper and/or gold and . Flotation is the usual mineral separation or concentration process of choice.Copper-Lead-Zinc ores - DanafloatCopper-Lead-Zinc ores. The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk.
